Let's divide 6860 by 21
Our goal is to divide 6860 by 21.

Let's proceed to step 1:
6 divided by 21 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 21

On to step 2:
21 goes into 68 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 63 from 68 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 21

Step 3:
21 goes into 56 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 42 away from 56, we end up with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 21

Step 4:
When dividing 140 by 21, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 326.0
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 5:
When dividing 140 by 21, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 326.6
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 6:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 326.66
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 326.66, and the remainder is 0.014.
